3 Claims. 1

My invention relates to a new and useful improvement in a filling spoutadapted for use on tanks. such as gasoline tanks to afford a means fordepositing the liquid in the tank.

An object of the invention is the provision in a filling spout having apair of telescoping tubes with the inner tube provided with a closurefor closing the outer end and all so constructed and arranged that whenthe inner tube is thrust inwardly its full length, the closure of itsouter end will lie flush with and in general appearance form acontinuation of the surface of a fender or the like through which thefilling spout is adapted to proceed.

Another object of the invention is the provision in a filling spouthaving an inner tube with a closed outer end provided with a grippingportion which is normally invisible.

Another object of the invention is the provision in a filling spouthaving a slidable inner tube with a closed outer end and provided on theouter surface of the closed end with a gripping portion corresponding tothe surface of the body through which the inn r spout is adapted toproject.

Another object of the invention is the provision in a filling spouthaving a pair of telescoping tubes of a novel construction relatingparticularly to the sealing.

Another object of the invention is the provision in a filling spouthaving a tube of a construction so arranged that the sealing gasket maybe sealed and quickly mounted therein.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made inthe detail of structure illustrated and it is intended that suchvariations may be encompassed within the scope of the claims which forma part hereof.

Forming a part of this specification are drawings in which Fig. 1 is acentral section or view of the invention with par-ts broken away andsome shown in side elevation.

Fig. 2 is a view similar to Fig. 1 with the inner tube in the extractedposition.

Fig. 3 is a fragmentary sectional view showing a slight modification.

Fig. 4 is a fragmentary sectional view showing a further modification.

In the drawing, I have illustrated the invention mounted on a tubularneck 9 which extends upwardly from a tank or container H]. An outer tubell formed preferably from sheet metal is connected by the flexiblesleeve l2 to the neck 9.

In the drawing, I have illustrated the invention used adjacentautomobile fender l3 having an opening it formed therein and punchedinwardly around the opening to provide the flange H5. The outer tube H ipressed outwardly at its upper end to provide the flange it which restsupon the upper face of the flange l5 and which may be suitably securedthereto by welding, soldering, riveting, or in any other suitable anher.The fender 5-3 thus serves as a supporting member for the outer tube l Iand when the outer tube 5 l is mounted on a fender as indicated, thefender itself serves as a covering or protective shield for the tube.

Formed in the inner face of the tube H, adjacent its upper end, is anannular groove I corresponding to a similar annular groove !8 formed onthe inner surface of tube l adjacent the lower end thereof. Formed inthe inner face of the tube I l adjacent its upper end is a groove l9,and seated in this groove It is a ring 2b of sealing material such asrubber, felt, leather, or the like. Slidably mounted in the tube l I isan inner tube 2! having a bead 22 formed on its inner end and providedwith a plurality of circumferentially spaced apart axially directedslots 23.

Formed in the inner tube El adjacent the outer end thereof is a lateralopening 24 which is exposed when the inner tube is drawn outwardly asshown in Fig. 2 to receive the nozzle of a filling hose.

The outer end of the tube 2! is turned outwardly to provide the radialflange 25 which is bent angularly as at 26 and thence radially as at 2?to provide a structure for gripping th ring 28 of sealing materialformed from rubber or other suitable material. When the tube 21 isthrust fully inwardly of the tube H the sealing ring 2!; will engage theflange iii and the bead will have snapped into the groove 18. When thetube ii is drawn outwardly as shown in Fig. 2 the bead 22 will havesnapped into the groove ll so that there is thus provided a yieldable orresilient means for resisting the movement of the tube 28 from open toclosed position and from closed to open position. In the slidablemovement of the tube 2% the ring 29 of sealing material will beartightly against the periphery of the tube 21 so as to prevent leakagearound the tube 2i.

A plate 29 serves as a closure for the outer end of tube 2! and restsupon and is suitably secured to the outer face of the flange 25. Asclearly shown in Fig. 1 when the tube 24 is moved to fully closedposition the outer face of the closure 29 lies flush and forms acontinuation of the outer face of the fender l3.

Formed in the closure 29 is a central opening 30 opening into a housing3| Positioned in this housing 3! is a spring 32 pressing the disc 33into position for closing the opening 30. When the tubes are in theposition shown in Fig. 1 and it is desired to pull the inner tubeoutwardly, the disc 33 is thrust inwardly by a persons finger againstthe compression of the spring 3! allowing the finger to grip the closure23 and draw the tube outwardly.

In Fig. 3 I have shown a slight modification,

A tube 2|A corresponds to the tube 2!, the flange 25A corresponds to theflange 25, and the ring 28A corresponds to the ring .28. The plate 29Acorresponds to the closure 29. This plate 29A is provided with anopening. 30A corresponds to the opening 30. A disc 33A corresponds tothe disc 33 and this disc 33A is pressed by the spring legs 34 intoclosing position, these spring legs being mounted on the crossbar 35.

In Fig. i, I have illustrated the invention in which the tube 25Bcorresponds to the tube 2i of Fig. 1. A closure 29B is mounted on thetube ZlB. Mounted on and extending across the closure 23B is a strip dcorresponding in contour to a decorative strip of moulding shown indotted lines. As shown the strip .0 has a raised portion to provide afinger grip. This illustration is presented to indicate the applicationof the invention to a structure which has a moulding strip mountedthereon.

What we claim as new is:

1. A filling spout of the class described, an outer tube; a supportingbody for said tube having an opening formed therein, said tube extendingout- Wardly from one side of said body and said opening; a flange onsaid body off-set inwardly therefrom around said opening and projectingradially of said outer tube to provide an inwardly off-set recess; anoutwardly projecting flange on the end of said outer tube engaging withand secured to the flange on said body; an inner tube slidably mountedin said outer tube, one end thereof projecting beyond the end of saidouter tube and extendable outwardly from the opposite side of said body;a securing structure on the outer end of said inner tube; a ring ofsealing material carried by said securing member and engaging, uponinward sliding of said inner tube into said outer tube, with the flangeof said outer tube for effecting a sealing engagement; a closure on theouter end of said inner tube, free from outward projections andextending outwardly beyond the periphery of said inner tube and lyingwith its outer surface flush with the surface of said surrounding bodywhen forming a continua tion of the contour thereof upon inward slidingof said inner tube its maximum distance and forming a closure for saidrecess.
